![]() With that simple algorithm, steps per second increases exponentially with linear speed setting increases. If, for example, the delay factor is in ms, 90 speed would produce 1/(1+10)ms per step = 90.9 steps per second, while 10 speed would be 1/(1+90)ms per step or 11 steps per second. At speed setting 90, the delay factor is 100-90=10, while at speed setting 10, it's 100-10=90. At speed setting 100, there is 0 delay so the motor is stepped at its highest speed (for example, if the step time was 1ms, the step rate would be 1/1ms per step, or 1000 steps per second). Unless your machine has servos for the axis drives, it probably has stepper motors and a common "speed" setting method for steppers is to vary the time between step pulses, such as. I don't recall any laser manufacturer ever characterizing their machines' complete speed and power curves but I've seen it repeated often enough that 100% power setting typically doesn't create ten times as much power as 10% power setting (but no idea whether it's more or less), and that 100% speed is not simply ten times 10% speed.
